Sleep research

The Wenatex Sleep System – developed in collaboration with sleep research experts

Around 50 million people living in Austria, Germany, Switzerland and Italy suffer from insomnia or sleep disorders. In the field of sleep research, there are now around 100 different types of diagnoses concerning sleep disorders. The World Health Organization (WHO) has declared these disorders – along with cardiovascular diseases, lung cancer and diabetes – to be among the four great challenges that medicine has to face over the next 50 years. Those suffering from sleep disorders are often ill-tempered, irritable and lack energy. Their quality of life is severely restricted. Additionally: sleep disorders are also one of the main causes of severe traffic accidents. Sleep deficiency has pretty much the same effect as drinking and driving.

Hence, it’s no wonder that great efforts are made in the field of sleep research in order to further invstigate the widespread disease of insomnia and to try and get the problem under control. Various sleep research experts, such as University Prof. Dr. Manfred Walzl, medical expert in the field of sleep research, confirm that, in addition to changes of lifestyle or changes regarding the intake of natural and chemical substances, the mattress and in fact the entire bed or sleep system is mainly responsible for determining the quality of sleep.


The new wenaCel® sensitive sleep system was developed in due consideration of the latest sleep research findings – hand in hand with an academic partner and confirmed by tests that were based on sleep medicine and supervised by University Prof. Dr. Manfred Walzl. It was of great interest to discover how the “wenaCel® sensitive” Sleep System is able to influence the individual sleep stages and how the Sanitized® Hygiene function and the application of TENCEL®, as well as the optimum aeration, the ergonomic characteristics, the five comfort zones, the anatomically correct sinking depth, the amazing support point elasticity and the remarkable breathability are able to influence both sleep in general and the individual sleep stages.

During the course of a year, from the beginning of October 2015 till September 2016, tests were carried out involving a total of 432 people, 213 of which used the new Wenatex Sleep System, while 219 people slept on conventional beds. With the aid of the latest screening methods applied in the field of sleep medicine, sleep research experts analysed the individual sleep stages and evaluated the respective influence of the Wenatex Sleep System.


The results of the study revealed clear advantages in favour of the Wenatex Sleep System: The stages of relaxed wakefulness, falling asleep and shallow sleep are reduced when sleeping on the wenaCel® sensitive Sleep System, while the duration of restful sleep stages or the REM sleep is increased.

  • In comparison with the control group, the relaxed wakefulness stage of the Wentax group was shortened by around 4.1 percent, the intermission stage between being awake and falling asleep (i.e. the stage of dormancy between going to bed and falling asleep) was even reduced by 8.2 percent.
  • The REM stages were increased by as much as 4.6 percent.
  • Even stages S1 (minus 3.9 percent) and S2 (minus 5.3 percent) were significantly reduced, while the regenerative stages S3 (plus 9.2 percent) and S4 (plus 8.7 percent) were considerably increased.


Falling asleep stage:

Condition of relaxed wakefulness, slight muscle activity, eyes roll around.

Stage 1 sleep:

This stage should actually only last for a few minutes. However, due to various forms of stress and strain, this stage is constantly expanding in the “modern” world. The muscles slowly begin to relax, arms and legs become heavier, the eyes close. But sounds or noises in the environment are still perceived by the brain.

Stage 2 sleep:

It’s quite easy to wake a person in this sleep stage The eyeballs are active moving to and fro. Many experts in the field of sleep research only consider this stage to be the actual beginning of sleep. The brain waves registered on EEG recordings show that consciousness gradually fades away during this stage.

Stage 3 sleep:

This is where deep sleep begins. Only extremely loud, piercing or rather unusual sounds are able to wake a person during this sleep stage. The muscles relax even further, heartbeat and breathing slow down to cruising speed and blood pressure is lowered. Nevertheless, a sleeping person can still show fast reactions if provoked by unusual stimulus.

Stage 4 sleep:

This is the deepest point of sleep in which it is relatively difficult to wake someone up. If it does become necessary to wake a person up during this stage or if a person is awakened by environmental stimuli, such as sound or motion, that person initially has difficulty in finding orientation and sometimes talks nonsense. The bodily functions are slowed down even further and the immune system begins the regenerate itself during this stage. The interesting point here: Tests have shown that persons subject to a considerable reduction of sleep are more prone to contract infections than those with a normal form of sleep behaviour. The point is: the most restful and regenerative sleep is attained during stage 4.

REM sleep:

This stage is in many ways similar to stage 1, but this is the stage in which we dream the most. The muscles are totally relaxed during this stage. Which, by the way, is actually quite a providential dispensation of nature. Just imagine what might happen if we wouldn’t lie in bed with our bodies in neutral during this stage, but if we were to physically act out whatever we experience in our dreams! The heartbeat and breathing now slowly begin to increase. The special characteristic of this stage, of course, are the rapid eye movements, which is where the abbreviation REM comes from. The brain is now working at full steam. If the brain activity is monitored with the aid of radioactive substances throughout the various stages of sleep, as well as during a state of wakefulness, REM sleep is the stage in which the brain is most active! If a person is awakened from this cycle of sleep, that person can often recall and relate his or her dreams.
